The silver halide photographic light-sensitive material in the image forming method of the present invention will be described. The halogen composition of the silver halide emulsion used in the silver halide emulsion layer of the photographic material is not particularly limited, but may be silver chloride, silver chlorobromide containing 60 mol% or more of silver chloride, or 60 mol% or more of chloride. It is preferable to use a silver halide emulsion having a composition of silver chloroiodobromide containing silver.

The average grain size of the silver halide is preferably 1.2 μm or less, more preferably 0.08 to 0.3 μm. The average particle size is a term that is commonly used by experts in the field of photographic science and is easily understood. The grain size means the grain diameter when the silver halide grains are spherical or can be approximated to spheres. If the particles are cubic, they are converted into spheres, and the diameter of the sphere is defined as the particle size. For details on how to determine the average particle size, see Mies and James:
The Theory of the Photographic Process by CE Mees & TH James: The
theory of the photographi
c process), 3rd edition, pp. 36-43 (196
6 (published by Macmillan, Inc.). The shape of the silver halide grains is not particularly limited, and may be any of a tabular shape, a spherical shape, a cubic shape, a tetradecahedral shape, a regular octahedral shape, and any other shapes. Further, a narrower particle size distribution is preferable, and a so-called monodisperse emulsion in which 90%, and preferably 95% of the total number of particles fall within a particle size range of ± 40% of the average particle size is particularly preferable.

The method of reacting the soluble silver salt with the soluble halide salt in the preparation of the silver halide emulsion may be any of a one-side mixing method, a simultaneous mixing method, and a combination thereof. A method of forming grains in the presence of excess silver ions (a so-called reverse mixing method) can also be used. As one type of the double jet method, a method of maintaining a constant pAg in a liquid phase in which silver halide is formed, that is, a so-called controlled double jet method can be used. To obtain a silver halide emulsion having a nearly uniform grain size.

In the present invention, the silver halide emulsion in at least one silver halide emulsion layer contains tabular grains, and the total of the projected areas of all grains in the emulsion layer in which the tabular grains are used is 50%. % Or more are preferably tabular grains having an aspect ratio of 2 or more. In particular, the ratio of tabular grains is 6
From 0% to 70%, further increasing to 80%, the better results are obtained. The aspect ratio represents the ratio of the diameter of a circle having the same area as the projected area of a tabular grain to the distance between two parallel planes.

Of these tabular grains, tabular grains having a (100) plane having 50 mol% or more of silver chloride as a main plane are preferably used, and these are described in US Pat. No. 5,26.

No. 0,958, and the like, and intended tabular grains can be easily obtained. In the tabular grains, silver halides having different compositions can be epitaxially grown or shelled at specific surface portions. In order to control the photosensitive nucleus, a transition line can be provided on the surface or inside of the tabular grains. In order to provide a transition line, fine grains of silver iodide can be present during chemical sensitization or can be formed by adding iodine ions. The preparation of the particles can be appropriately selected from an acid method, a neutral method, an ammonia method and the like. When doping a metal, it is particularly preferable to form particles under acidic conditions of pH 1 to 5. As a silver halide solvent, for example, ammonia, a thioether, a thiourea compound, a thione compound, or the like can be used to control the growth of the grains during the formation of tabular grains.

Rhodium, ruthenium, osmium and / or
Alternatively, the rhenium compound is preferably added during the formation of silver halide grains. As the addition position, there is a method of distributing uniformly in the particles, a method of forming a core-shell structure, and a method of localizing a large amount in the core portion or the shell portion.

A better result is often obtained when a large amount is present in the shell portion. Alternatively, a method may be used in which the abundance is increased as the particles become continuously outside the particles, instead of being localized in a discontinuous layer structure. The addition amount can be appropriately selected from the range of 10 ^-9 mol to 10 ^-3 mol per mol of silver halide.
